Grundfos Sewage Pumps Overview
Grundfos sewage pumps cover an exceptionally wide operating range, from compact submersible units delivering approx 360-1,200 l/min (0.6-2 m³/h) for localized wastewater handling, up to large municipal and industrial pumps reaching around 113,400 l/min (6,800 m³/h). Across the range, maximum heads range from 7 m to 116 m, with motor power starting at ≈0.7 kW (≈1 HP) and rising to over 520 kW (≈700 HP). Designed for continuous duty, these pumps handle wastewater, sewage, sludge, and raw sewage at liquid temperatures typically 0-40 °C.
